Recently,much interest has been given tomulti-granulation rough sets (mGRS), and various types ofmGRSmodelshave been developed from different viewpoints. In this paper, we introduce two techniques for the classificationof mGRS. Firstly, we generate multi-topologies from multi-relations defined in the universe. Hence, a novelapproximation space is established by leveraging the underlying topological structure. The characteristics of thenewly proposed approximation space are *** introduce an algorithmfor the reduction ***, a new approach for the classification ofmGRS based on neighborhood concepts is introduced. Finally, areal-life application from medical records is introduced via our approach to the classification of mGRS.

为提高磁流变制动器制动能效,提出一种多盘连续可变磁流变液工作间隙结构的磁流变制动器。在ANSYS workbench环境下完成不同电流、间隙状态下的三维静态磁场仿真,对磁场沿工作间隙分布状况进行分析,通过试验台架对制动器性能进行测试。结果表明,磁流变液工作区域磁矢量分布相对均匀,无明显积聚现象,磁路设计合理。理论与实验结果变化趋势基本吻合,但在电流较大时,两者之间误差呈逐渐增大趋势。制动力矩在0~2.5 A电流变化区间增速较快,而在2.5~4.0 A区间明显放缓,最大力矩达到146.4 N·m,较间隙未改变状态增加25.80%。设计的制动器TVR值达到48.81 kN·m/m^(3),较传统磁流变制动器结构更紧凑,力矩调节范围更广,设计思路及实验结论对磁流变制动器结构的进一步研究具有借鉴意义。

Open Journal of Animal Sciences 2024年第2期14卷 39-55页

The aim of the present study was to determine the prevalence of bovine cysticercosis in both cattle and buffloas, in Egypt and to assess the cysticidal efficacy of Balanites aegyptiaca fruits (B. aegyptiaca) and moringa oleifera seeds (m. oleifera) extracts in experimentally infected mice. The study detected the level of tumor necrosis factor (TNF-α) to monitor the immune and inflammatory responses of experimentally infected mice. Through meat inspection, a total number of 2125 male bovine, 2 to 5 years old, (1125 cattle and 1000 buffloes) were examined under the authority of Albsatine and Alwaraq official abattoirs in Cairo Governorate, Egypt covering the period extended from march 2022 to April 2023. The overall prevalence of the disease among bovine was 7.8% (6.31% of cattle and 9.5% of buffloes). Besides, B. aegyptiaca and m. oleifera extracts showed cysticidal activity in experimentally infected mice. A decrease in the numbers of cysticerci was found in all treated mice groups, and up to 88% reduction was achieved in the B. aegyptiaca-treated group;higher than that was recorded in both m. oleifera (72.23%) and albendazole-treated ones (80.56%). Postmortem findings proved that m. oleifera and B. aegyptiaca reduced cysticerci numbers comparable to a commercial anthelmintic. The study showed a significant decrease (P 0.001) in TNF-α levels after treatment with Balanites and moringa extracts, compared with the untreated control and the albendazole-treated groups.
